Description

Insulator

The present invention relates to an insulator. The present invention relates to a refrigerator equipped with an insulator.

Japanese Patent Application Publication JP2013-002656A (published on January 7, 2013; hereinafter referred to as “Patent Document 1”) discloses a refrigerator capable of reducing the number of manufacturing processes.

The refrigerator disclosed in Patent Document 1 has an insulating case composed of a vacuum insulating panel arranged between an outer case and an inner case. The inner case has a protrusion that protrudes into the interior. The protrusion is formed integrally with the inner case. The protrusion has a shelf support portion, a guide rail installation portion, and a partition wall support portion, and can support and combine parts such as shelves, drawers, and partition walls that are combined into the interior of the refrigerator. Patent Document 1 has a problem in that it is difficult to form the protrusion integrally with an inner case formed of a metal material.

According to patent document 1, a sheet member connecting portion is formed integrally with an inner case of a vacuum insulation panel. However, in this case, the sheet member connecting portion is thicker than the thickness of the inner case, making it difficult to manufacture a vacuum insulation panel in which the sheet member connecting portion and the inner case are formed integrally.

The purpose of the present invention is to provide a refrigerator having a structure capable of solving the above-described problems.

The first purpose is to provide a refrigerator having a structure capable of reinforcing insulation at corners where multiple vacuum insulators are connected.

The second purpose is to provide a refrigerator having a structure that can expand the insulation area without affecting the internal volume.

The third objective is to provide a refrigerator having a structure in which joints and additional insulation blocks can be easily joined.

The fourth purpose is to provide a refrigerator having a structure in which joint and insulation blocks can be uniformly adhered to a second case of a vacuum insulator.

The fifth purpose is to provide a refrigerator having a structure in which shelf hanging plates or drawer guides can be easily combined to provide parts such as shelves or drawers inside the refrigerator to which vacuum insulation panels are applied.

The sixth purpose is to provide a refrigerator having a structure in which joints and insulation blocks can be evenly attached to a second case of a vacuum insulator by using internal parts such as shelf hanging plates and drawer guides.

The refrigerator of the present invention may include at least one panel. A plurality of said panels may be connected by joints. The present invention may include a first panel forming a first side (e.g., a side) of the refrigerator. Optionally, the present invention may include a second panel forming a second side (e.g., a back) of the refrigerator. Optionally, the present invention may include a third panel forming a third side (e.g., a top) of the refrigerator. Optionally, the present invention may include a fourth panel forming a fourth side (e.g., a bottom) of the refrigerator. Each of the first, second, third and fourth panels may be provided in plurality. The panels may be insulators or vacuum insulators. The first panel may include one of the first panels forming one of the first sides of the refrigerator, and another of the first panels forming the other of the second sides of the refrigerator. At least one of the first, second, third and fourth panels may provide at least a portion of a wall forming a storage compartment of the refrigerator. At least one of the first, second, third and fourth panels can provide at least a portion of a wall forming the main body of the refrigerator.

According to one embodiment of the present invention, a refrigerator includes a main body. The main body has a second storage compartment. The main body includes a first plate, a second plate, and a support. The first plate is arranged toward the second storage compartment. The second plate is arranged toward the outside of the second storage compartment. The support forms a vacuum space between the first plate and the second plate and supports the first plate and the second plate. The main body includes a second storage compartment joint and/or a component joint. The second storage compartment joint is formed of a different material from the first plate. The second storage compartment joint is arranged at a corner portion where at least two panels forming the second storage compartment are connected. The component joint connects the second storage compartment joint to the first plate at the corner portion. According to this configuration, the second storage compartment joint can reinforce insulation at a corner portion where a plurality of vacuum insulators are connected. It is possible to easily join joints and additional insulation blocks through the above-mentioned component joints.

A joining portion is formed to protrude from one side of the second storage joint. The joining portion has a joining hole. The component joining portion includes a bolt plate and a bolt portion. The bolt plate is joined to the first plate. The bolt portion protrudes from the bolt plate. The bolt portion penetrates the joining hole. A nut is joined to the bolt portion. Accordingly, the second storage joint can be easily joined by joining the bolt plate and the joining portion.

The above-mentioned component joint includes a support portion and a hook portion. The support portion is connected to the bolt plate by the bolt portion. The support portion is configured to support the evaporator. The hook portion is formed to protrude in a ring shape from the support portion so that a part of the evaporator is hung. Through this, the hook portion of the component joint can easily install and dismantle the evaporator.

The above-described component joint includes a first movement-limiting portion that extends in one direction (e.g., forward) from an edge portion of the support portion to limit one-way movement of the second storage joint. The above-described component joint may include a second movement-limiting portion that limits another one-way movement of the second storage joint. The second movement-limiting portion may be formed to extend in one direction so as to cover a portion of the second storage joint from one side of the first movement-limiting portion. Through this, the above-described component joint may support the second storage joint in various directions.

The first joint includes a recessed portion that is formed to slope from a peripheral portion of one side of the first joint toward a central portion of one side of the first joint. The first joint may include a penetrating portion that is formed to penetrate one direction through the central portion of the recessed portion so as to discharge condensate generated in the evaporator to the outside. Through this, the penetrating portion of the second storage chamber joint can discharge condensate generated in the evaporator to the outside.

The above-mentioned component joint may include a third plate coupled to the first plate so as to cover the second storage joint. Through this, the third plate can more firmly couple the second storage joint.

The materials of the first plate and the second storage joint may be provided differently. The first plate may be formed of a metal material, and the second storage joint may be formed of at least one insulating material among PU, ABS, and EPS. Through this, the insulating performance of the refrigerator may be improved.

The at least two panels may include an insulating block extending from a corner portion where they are connected. In this way, the insulating block can expand the insulating area of the refrigerator without affecting the high internal capacity.

The above insulation block may be provided as a separate part to the second storage room joint and joined, or may be formed as an integral part. Through this, the second storage room joint and the insulation block can be easily installed and dismantled.

The sealing frame may be provided in multiple pieces. The multiple sealing frames may be arranged spaced apart in one direction along one side of the insulating block. Through this, the sealing frame may support a part of the insulating block (e.g., the front part and/or the rear part) by sealing it.

Optionally, the present invention may be provided with a drawer guide that is coupled to one side of the insulating block and protrudes to guide the movement of a drawer introduced or withdrawn from the second storage room. The contact frame may be arranged between the insulating block and the drawer guide. Through this, the contact frame can contact the drawer guide together with the insulating block.

Optionally, the present invention comprises a first storage compartment and a second storage compartment. Optionally, the present invention comprises a second storage compartment joint disposed at a corner portion where a plurality of the panels forming the second storage compartment are connected. An insulating block may be provided that is formed integrally with the second storage compartment joint or is provided as a separate part and is combined so as to cover one surface of the first panel, the second panel, and the fourth panel. A sealing frame may be provided that is combined to one surface of the insulating block and seals the second storage compartment joint and the insulating block to one surface of the refrigerator body. Through this, the sealing frame can easily seal the second storage compartment joint or the insulating block. Since the sealing frame does not require a bolt plate, it not only blocks heat from leaking through the corner, but also is advantageous in improving insulation performance.

According to an embodiment of the present invention, the following effects can be achieved.

First, the body of the refrigerator is manufactured by assembling at least two panels made of vacuum insulation, and a joint made of insulation is arranged at the corners where a plurality of vacuum insulation panels are connected to reinforce the insulation of the corners.

Second, a bolt plate is installed on one side of at least two panels, and a bolt portion is formed protrudingly on the bolt plate. A joint is provided with a joining portion having a joining hole formed in the joint. The bolt portion penetrates the joining hole of the joining portion, and as the nut is joined to the bolt portion, the joint can be easily joined to one side of the main body, such as the third panel, by the bolt plate.

Third, the insulation block can be formed integrally at the joint. The insulation block can be expanded to the insulation area of the joint. The insulation block can be placed utilizing a space that does not change the high internal capacity of the refrigerator.

Fourth, the insulating blocks can be joined by bolt plates installed on one side of the main body. A joining hole is formed in the insulating block. The bolt portion of the bolt plate penetrates the joining hole of the insulating block, and as the nut is joined to the bolt portion, the insulating block can be easily joined to one side of the main body, such as the third panel, the first panel, and the second panel, by the bolt plate.

Fifth, the close frame can be joined to one side of the insulating block in which the joint or joint is formed integrally. A joining hole is formed in the close frame. The bolt portion of the bolt plate penetrates the joining hole of the insulating block and the joining hole of the close frame, and as the nut is joined to the bolt portion, the close frame can close-join the insulating block to one side of the main body. An extension rib can be extended along the longitudinal direction of the joint. The close frame can close-join the joint to one side of the main body by pressing the extension rib or directly pressing the joint.

Sixth, parts arranged inside the main body, such as shelves, drawers, etc., may be provided with separate part joining parts so as to be joined to one side of the main body. A shelf hanging plate or a drawer guide having a through hole may be easily joined to one side of the main body by a bolt plate. The bolt portion of the bolt plate passes through the joining hole of the shelf hanging plate, and as a nut is joined to the bolt portion, the shelf may be easily joined to one side of the main body. The bolt portion of the bolt plate passes through the joining hole of the drawer guide, and as a nut is joined to the bolt portion, the drawer guide may be easily joined to one side of the main body.

Seventh, since the end of the sealing frame is connected to the partition wall, the end of the sealing frame is connected to the fourth block portion, which is an insulating block of the fourth panel, and the sealing frame and the drawer guide are connected by the bolt portion of the bolt plate, the sealing frame can easily seal the drawer guide to one side of the first panel and the second panel.

Eighth, the sealing frame is joined to one side of the insulation block formed integrally with the second storage room joint. Through this, the sealing frame can easily join the second storage room joint or the insulation block to one side of the main body. Since the sealing frame does not require a bolt plate, it not only blocks heat leakage through the corner, but also is advantageous in improving insulation performance.

A component joint is provided inside the main body (100). The component joint is configured to join components arranged on one side of the main body (100). For example, the component joint can join a joint (110) to be described later.

In this embodiment, the component joint may include a bolt plate (109). The component joint may use the bolt plate (109) to join a component such as a joint (110) to one surface of the main body (100). The bolt plate (109) is formed in a plate shape.

The bolt plate (109) is installed toward the storage room on one of the second panel (101) and the first panel (1031) and/or the other of the first panels (1032). The bolt plate (109) can be bonded to the first plate (1081) of each of the second panel (101) and the first panel (1031, 1032) by an adhesive or welding, etc.

The first plate (1081) constituting the vacuum insulator (108) is arranged toward the inside of the main body (100). The second plate (1082) constituting the vacuum insulator (108) is arranged toward the outside of the main body (100).

The joint (110) may be formed of one or a combination of two or more selected from among, for example, PU (polyurethane), ABS (acrylonitrile, butadiene, styrene), and EPS (expandable polystyrene). Through this, when at least two panels made of vacuum insulators are assembled together to form the main body (100) of the refrigerator, and the first plate (1081), which is the second case of the vacuum insulator, is formed of a metal material, the joint (110) can minimize the leakage of cold air (heat) from the storage room to the outside of the main body (100) and secure insulation performance.

The joint (110) can reinforce the insulation of the corner portion where a plurality of vacuum insulators (108) are connected.

The joint (110) may include a joint cover (111) and a joint insulator (112). The joint insulator (112) is made of an insulating material such as PU. The joint cover (111) is made to surround the joint insulator (112). The joint cover (111) may be formed of a plastic material.

In order to connect the joint (110) to one side of the main body (100), a connecting portion (1164, 118, 124) may be provided on one side of the joint (110). The connecting portion (1164, 118, 124) may include a connecting hole. The connecting portion (1164, 118, 124) is connected to the component connecting portion through the connecting hole, thereby connecting the main body (100) and the joint (110).

The joint (110) includes an extension rib (114). The extension rib (114) may be formed integrally with the joint (110). The extension rib (114) may extend along the longitudinal direction of the joint (110). The length of the extension rib (114) is formed to be longer than the width of the extension rib (114). The length of the extension rib (114) may be formed to be equal to or smaller than the length of the joint (110).

A portion of the connecting portion (1164, 118, 124) may be arranged to overlap a portion of the extension rib (114) so that a portion of the connecting portion (1164, 118, 124) covers a portion of the extension rib (114).

Through this, the joint (1164, 118, 124) can receive a pressing force from the component joint to pressurize and seal the joint (110) and the extension rib (114) toward one side of the main body (100), that is, the first plate (1081) of the vacuum insulator (108).

, one side (e.g., the left end or the right end) of the extension rib (114) may be arranged to be connected in the Y-axis direction to one side (e.g., the right end or the left end) of the bolt plate (109).

Through this, the extension rib (114) can be restricted from moving in the Y-axis direction by the bolt plate (109). The joint portion can improve the adhesion between one surface of the main body (100) and the joint (110).

The joint (110) can be divided into a first storage room joint (115) provided on one side of the first storage room (105) and a second storage room joint (120) provided on one side of the second storage room (106).

Referring to FIG. 7, the first storage joint (115) may include a first joint (116) arranged at a corner portion where the second panel (101) and the third panel (102) are connected.

The first joint (116) is formed to extend along the Y-axis direction of the second panel (101). The first joint (116) is formed to connect the second panel (101) and the third panel (102). The first joint (116) may have a triangular cross-sectional shape.

Both ends of the first joint (116) can be connected to one of the first panels (1031) and the other of the first panels (1032), respectively.

The third side of the first joint (116) is formed to extend in a diagonal direction so as to connect the ends of each of the first side and the second side. The third side of the first joint (116) can be arranged toward the storage room.

A first coupling portion (1164) may be provided in the first joint (116). The first coupling portion (1164) is formed in a plate shape. The first coupling portion (1164) may extend in a protruding direction from the second surface of the first joint (116). The first coupling portion (1164) has a coupling hole.

The first connecting portion (1164) is arranged to cover the end of the first bolt plate (1091). The end of the first connecting portion (1164) and the first bolt plate (1091) are arranged to overlap in the X-axis direction.

The bolt portion (1095) positioned at the end of the first bolt plate (1091) can be connected to the first connecting portion (1164) by penetrating the connecting hole of the first connecting portion (1164). A connecting member such as a nut can be connected to the bolt portion (1095), so that the first joint (116) can be connected to the first plate (1081) of the second panel (101).

However, instead of the bolt plate (109) equipped with a bolt portion (1095), a nut plate equipped with a nut portion may be installed on the first plate (1081) of the second panel (101). In this case, a connecting member such as a bolt or the like may be connected to the nut portion, and the first joint (116) may be connected to the first plate (1081) of the second panel (101).

The first storage joint (115) may include a second joint (117) arranged at a corner portion where the second panel (101) and the first panel (1031, 1032) are connected.

The second joint (117) is arranged at the end of the second panel (101). Since the second joint (117) has a triangular cross-sectional shape and is similar to the configuration of the first joint (116), a duplicate description will be omitted.

The first side of the second joint (117) can be connected to one side of one of the first panels (1031) and/or the other side of the first panels (1032). The second side of the second joint (117) is connected to one side of the second panel (101). The third side of the second joint (117) extends diagonally to connect the first side and the second side of the second joint (117).

The second connecting portion (118) may be formed to protrude from one side of the second joint (117). The second connecting portion (118) may be formed in a plate shape. A connecting hole is formed in the second connecting portion (118).

The second connecting portion (118) may be arranged to cover an end of the first bolt plate (1091). The end of the second connecting portion (118) and the first bolt plate (1091) may be arranged to overlap in the X-axis direction.

A bolt portion (1095) positioned at an end of the first bolt plate (1091) can be connected to the second connecting portion (118) by penetrating the connecting hole of the second connecting portion (118). A connecting member such as a nut can be connected to the bolt portion (1095), and the second joint (117) can be connected to the first plate (1081) of the second panel (101).

An end of the second joint (117) can be connected to one side of a partition wall (107; see Fig. 16).

An extension rib (114) may be further provided on the second surface of the second joint (117). The extension rib (114) may be formed to protrude to one side (e.g., toward the left or right) at the point where the second surface and the third surface of the second joint (117) meet. The extension rib (114) may be formed integrally with the joint cover (111) of the second joint (117).

The extension rib (114) extends along the length of the second joint (117). One end of the extension rib (114) may be connected to or overlapped with an end of the first bolt plate (1091).

The first connecting portion (1164) of the first joint (116) may be arranged to cover the first bolt plate (1091) and the extension rib (114) of the second joint (117). A connecting member such as a nut may be connected to the bolt portion (1095) to firmly maintain the connecting force of the first joint (116), the second joint (117) and/or the first bolt plate (1091).

, when the first connecting portion (1164) of the first joint (116) and the first bolt plate (1091) are connected, the first connecting portion (1164) presses the extension rib (114) of the second joint (117), thereby obtaining the effect of bringing the second joint (117) into close contact with one surface of the second panel (101) and/or one surface of the first panel (1030, 1032).

The extension rib (114) wraps around one side of the first bolt plate (1091), thereby minimizing heat leakage through the bolt plate (109).

The first storage joint (115) may include a third joint (119) arranged at a corner portion where the third panel (102) and the first panel (1031, 1032) are connected.

The third joint (119) is formed to extend in the X-axis direction of the side panel (103). The third joint (119) is positioned at each end of the first panel (1031, 1032). The second joint (117) has a triangular cross-sectional shape, which is similar to the configuration of the first joint (116), so a duplicate description will be omitted.

The first side of the third joint (119) can be connected to one side of the side panel (103). The second side of the third joint (119) is connected to one side of the third panel (102). The third side of the third joint (119) extends diagonally to connect the first side and the second side of the third joint (119).

The end of the third joint (119) facing in the opposite direction to the door is connected to the end of the first joint (116) and the end of the second joint (117). A connecting portion is further provided at the end of the third joint (119). The connecting portion may be formed to be inclined so as to be connected while facing the third surface of the first joint (116). The connecting portion of the third joint (119) and the end of the first joint (116) are connected to each other.

One end of the second joint (117) can be connected to an end of the first joint (116) and/or an end of the third joint (119). The second joint (117) can support the first joint (116) and/or the third joint (119).

The first storage joint (115) can be assembled in the order of the second joint (117), the first joint (116), and the third joint (119).

Referring to FIGS. 7 and 8, the second storage joint (120) may include a first joint (121) arranged at a corner portion where the fourth panel (104) and the second panel (101) are connected.

The first joint (121) is formed to extend in the Y-axis direction. The first joint (121) is formed to connect the fourth panel (104) and the second panel (101). Both ends of the first joint (121) can be connected to the first panel (1031, 1032).

The first joint (121) may have a cross-sectional shape of a square or pentagon. In the present embodiment, the first joint (121) has a cross-sectional shape of a pentagon. Among the five side surfaces of the first joint (121), the first side (1211) may be connected to one side of the fourth panel (104). The first side (1211) of the first joint (121) may form one side of the first joint (121).

A receiving groove (1212; see Fig. 20) may be formed in a part (e.g., the front side) of the first joint (121). The receiving groove (1212) is a fourth panel exhaust port receiving groove for receiving the fourth panel exhaust port (1224). The receiving groove (1212) may be formed to be open in one direction.

The fourth panel exhaust port (1224) is accommodated in the receiving home (1212). Through this, the first joint (121) surrounds the fourth panel exhaust port (1224), thereby blocking the fourth panel exhaust port (1224) and cold air from the second storage room (106) from coming into contact, thereby improving insulation performance.

The second side (1212) of the first joint (121) can be formed to be connected to one side of the second panel (101). The second side (1212) of the first joint (121) can form the rear surface of the first joint (121).

A plurality of holes (1214, 1216) may be formed sunken into the second surface (1212) of the first joint (121). Among the plurality of holes (1214, 1216), the first hole (1214) is an exhaust port receiving hole formed to exhaust air in order to form a vacuum insulator (108) of the second panel (101).

The third panel exhaust port (1215) is accommodated in the first hole (1214). Through this, the first joint (121) surrounds the third panel exhaust port (1215), thereby blocking contact between the third panel exhaust port (1215) and cold air in the second storage room (106), thereby improving insulation performance.

Among the plurality of holes (1214, 1216), the second hole (1216) may be a hole for forming a suction line heat exchanger (hereinafter, SLHX) outlet. The suction line is a refrigerant pipe connected between the evaporator (148) and the compressor, and sucks the refrigerant that has passed through the evaporator (148) into the compressor. The SLHX is configured by welding a capillary tube to the outer surface of the suction line by soldering or the like. Through this, the SLHX connects the capillary tube and the suction line to each other on the suction side of the compressor by surface area to perform heat exchange.

A suction pipe heat exchanger outlet (1217) is accommodated in the second hole (1216). Through this, the first joint (121) surrounds the suction pipe heat exchanger outlet (1217), thereby preventing the suction pipe heat exchanger outlet (1217) and the cold air of the second storage room (106) from coming into contact, thereby improving the insulation performance.

A plurality of holes (1214, 1216) may be arranged spaced apart from each other in the Y-axis direction. The first and/or second holes (1214, 1216) may be formed to be open toward one side of the second panel (101). A suction pipe connection hole may be further formed to penetrate through the second hole (1216) in one direction.

A support surface may be formed on a part (e.g., left and right ends) of the third surface (1218) of the first joint (121). The support surface is formed in a flat shape. The support surface is configured to support the second joint (123) described later.

A recessed portion (1219) may be formed to be sunken in one direction on the third surface (1218) of the first joint (121). A penetrating portion (1220) may be formed to penetrate in the Z-axis direction in the central portion of the recessed portion (1219). A portion (e.g., left side and/or right side) of the recessed portion (1219) is formed to be inclined in one direction (e.g., downward) from the support surface toward the penetrating portion (1220).

The defrost water generated in the evaporator (148) can be drained through the through-hole (1220). An overflow prevention plate (1221) is provided at the end of the recessed portion (1219). The overflow prevention plate (1221) is configured to block a part (e.g., the front side) of the recessed portion (1219). Through this, the overflow prevention plate (1221) can prevent the defrost water accumulated in the recessed portion (1219) from overflowing into the first joint (121).

The fourth surface (1222) of the first joint (121) may form a part of the first joint (121). The fourth surface (1222) of the first joint (121) may be formed to be inclined downward from the third surface (1218). The fourth surface (1222) of the first joint (121) may not only increase the internal volume, but also enable smooth convection of cold air in the second storage room (106).

The fifth side (1223) of the first joint (121) can form another part of one side of the first joint (121). The fifth side (1223) of the first joint (121) can extend in one direction (e.g., vertically) from the fourth side (1222). The fifth side (1223) of the first joint (121) can provide one side for connection to an additional insulator.

Referring to FIG. 8, the second storage joint (120) may include a second joint (123) arranged at a corner portion where the first panels (1031, 1032) are connected.

The second joint (123) may be arranged at an end of the second panel (101). The second joint (123) may be formed to extend in the Z-axis direction. The second joint (123) may have a polygonal cross-sectional shape. In the present embodiment, the second joint (123) is shown to be formed in a heptagonal cross-sectional shape.

Among the seven sides of the second joint (123), the first side (1231) forms the rear surface of the second joint (123). The first side (1231) of the second joint (123) can be formed to face and be connected to one surface of the second panel (101).

The second side (1232) of the second joint (123) can form one side (e.g., the left side and/or the right side) of the second joint (123). The second side (1232) of the second joint (123) can be formed to face and be connected to one side of one of the first panels (1031) or the other of the first panels (1032).

The third surface (1233) of the second joint (123) extends in one direction (e.g., forward) from the first surface (1231). The third surface (1233) is positioned opposite the second surface (1232) in the Y-axis direction. The extension length of the third surface (1233) is smaller than the extension length of the first surface (1231) or the second surface (1232). The third surface (1233) of the second joint (123) is in contact with one surface of a space that accommodates the evaporator (148), thereby preventing leakage of cold air (heat) generated from the evaporator (148).

The fourth surface (1234) of the second joint (123) extends in the Y-axis direction from the third surface (1233) toward the second surface (1232). The fourth surface (1234) is arranged opposite to the first surface (1231) in the X-axis direction. The extension length of the fourth surface (1234) is smaller than the extension length of the first surface (1231) or the second surface (1232).

One side of the return duct can be arranged to be connected to the fourth side (1234). The return duct forms a path for cold air to be returned from the first storage room (105) to the second storage room (106).

The fifth side (1235) of the second joint (123) extends obliquely from one end of the fourth side (1234) to one end of the sixth side (1236) to be described later with respect to the fourth side (1234). The other end of the return duct can be arranged to be connected to the fifth side (1235).

The sixth side (1236) of the second joint (123) extends in one direction (e.g., forward) from the other end of the fifth side (1235). The sixth side (1236) is arranged to face the second side (1232). The extension length of the sixth side (1236) is smaller than the extension length of the first side (1231) or the second side (1232). Another side of the return duct may be arranged to be connected to the sixth side (1236).

The seventh surface (1237) of the second joint (123) extends in the Y-axis direction from the second surface (1232). The seventh surface (1237) is arranged to face the first surface (1231) in the X-axis direction. The seventh surface (1237) is arranged to be connectable to one surface of an additional insulator.

An end of the second joint (123) can be connected so as to be connectable to one side of the partition wall (107).

A third connecting portion (124) may be provided on at least one of the first end and the second end of the second joint (123). The third connecting portion (124) may be formed to protrude in one direction from the first surface (1231) of the second joint (123). The third connecting portion (124) is formed in a plate shape. A connecting hole is formed in the third connecting portion (124). The third connecting portion (124) may be connected by a bolt portion (1095) protruding from an end of a first bolt plate (1091) located on one side. The bolt portion (1095) penetrates the connecting hole of the connecting portion, and a nut is connected to the penetrated bolt portion (1095), so that the second joint (123) may be connected to the first plate (1081), which is one surface of the second panel (101).

The second storage joint (120) may include a third joint (127) positioned at the corner where the fourth panel (104) and the first panel (1031, 1032) are connected.

The third joint (127) may be formed to extend in the X-axis direction from the end of the first joint (121). The third joint (127) may have a polygonal cross-sectional shape.

In this embodiment, the third joint (127) is shown as having a pentagonal cross-section. For example, the third joint (127) may include the first to fifth sides.

The first side is formed to be connected to the fourth panel (104). The second side is formed to be connected to one of the first panels (1031) and/or the other of the first panels (1032). The third side can extend in one direction from the first side. The third side is arranged to face the second side. The one-way height of the third side can be smaller than the one-way height of the second side.

The fourth side is formed to be inclined from the third side toward one of the first panels (1031) and/or the other of the first panels (1032). The fifth side is formed to extend in the Y-axis direction from the fourth side toward one of the first panels (1031) and/or the other of the first panels (1032). The fifth side is arranged to face the first side. The Y-axis width of the fifth side may be smaller than the Y-axis width of the first side.

A plurality of side panel exhaust ports (1274) may be formed on an end portion of one side of one of the first panels (1031) and/or the other side of the first panels (1032). A side panel exhaust port receiving groove (1273) may be formed on a second surface of the third joint (127) of the second storage chamber joint (120). In this way, the third joint (127) surrounds the side panel exhaust port (1274), thereby blocking contact between the side panel exhaust port (1274) and cold air in the second storage chamber (106), thereby improving insulation performance.

The second storage joint (120) can be assembled in the order of the first joint (121) to the third joint (127). However, the order is not limited to this order.

In the connecting portion (1164, 118, 124), the connecting projection (128) may be formed to protrude in one direction (e.g., forward). The connecting projection (128) may be formed to protrude in a circular shape so as to surround the connecting hole. The wall of the connecting projection (128) may be formed in a polygonal shape, such as a hexagon. Accordingly, when the bolt portion (1095) passes through the connecting hole and a connecting member, such as a nut, is connected to the bolt portion (1095), the wall of the connecting projection (128) surrounds the wall of the nut and engages, thereby preventing the nut from loosening.

The joining projection (128) can reinforce the rigidity of the joining part when the plate thickness of the joining part is thin.

A gap may be formed between the outer wall of the coupling projection (128) and the third surface of the second joint (123). The reason for providing a gap between the outer wall of the coupling projection (128) and the third surface of the second joint (123) is to provide a tool insertion space for tightening the nut.

The coupling projection (128) can be applied not only to the first and second joints (121, 123) of the second storage room joint (120), but can also be applied identically or similarly to the first storage room joint (115).

A third plate (143)(129) can be attached to the first plate (1081). The third plate (143)(129) can reinforce the rigidity of the first plate (1081).

The third plate (129) can be arranged to overlap the bolt plate (109) in the X-axis direction. This can reinforce the rigidity of the vacuum insulation body (108) when the bolt plate (109) is bolted.

Since other components are identical or similar to the embodiments of FIGS. 1 to 13 described above, duplicate descriptions will be omitted.

The bolt portion (1095) of the bolt plate (109) passes through the joining hole, and as the nut is joined to the bolt portion (1095), the first part joining portion (131) can be joined to one side of the second panel (101) by joining the second part (133) and the bolt plate (109).

Among the plurality of side walls (1321, 1322) of the first component joint (131), one first side wall (1321) may be formed to have a shorter protrusion length than the second side wall (1322) of the other one of the plurality of side walls (1321, 1322). An end of the second side wall (1322) may be connected to the second part (133).

At the end of the first side wall (1321), a sealing portion (1325) can extend toward the second joint (117).

The sealing portion (1325) may extend in the Z-axis direction along the end of the first side wall (1321). The sealing portion (1325) may be arranged to overlap with the extension rib (114) in the X-axis direction so as to cover the extension rib (114) of the second joint (117).

When the first part joint (131) is joined, the contact portion (1325) can receive a one-way (e.g., rearward) pressing force from the second part (133) and/or the first part (132) to contact the second joint (117) to one side of the second panel (101).

A multi-duct (134) may be provided on one side of the main body (100). The multi-duct (134) may be placed in the first storage room (105). The multi-duct (134) forms a cold air path on one side. The multi-duct (134) may be connected to communicate with the second storage room (106). An evaporator (148) may be installed on the second panel (101) of the second storage room (106).

Through this, the multi-duct (134) can move the cold air from the second storage room (106) cooled by the evaporator (148) to the first storage room (105).

A shelf hanging penetration portion (1341) may be formed in a portion (e.g., left and right ends) of the multi-duct (134). The shelf hanging penetration portion (1341) is formed to penetrate in the X-axis direction so as to communicate with the through hole (1324). The shelf hanging penetration portion (1341) is formed to be inclined in one direction (e.g., forward) on one side of the second panel (101) so as to cover the bolt portion (1095) of the bolt plate (109).

A joint cover part (1342) may be provided on a part (e.g., left and right ends) of the multi-duct (134). The joint cover part (1342) is configured to cover the second joint (117). The joint cover part (1342) may be joined so that the multi-duct (134) is forcibly fitted between one side of the first panel (1031, 1032).

The joint cover part (1342) of the multi-duct (134) may include an inclined part (1343). The inclined part (1343) of the multi-duct (134) is formed to be inclined at an angle corresponding to the third surface of the second joint (117) and may come into surface contact with the third surface of the second joint (117) and pressurize the third surface of the second joint (117).

The multi-duct (134) may include an insertion portion (1344) and a pressurizing portion (1345).

The insertion portion (1344) can extend in one direction (e.g., rearward) from one end of the joint cover portion (1342) so as to overlap with the first side wall (1321) portion of the first component joint portion (131) in the Y-axis direction. The pressurizing portion (1345) extends from a part (e.g., rear end) of the insertion portion (1344) so as to overlap with the sealing portion (1325) in the X-axis direction.

When the multi-duct (134) is fitted and connected to one side of the main body (100), the pressurizing portion (1345) receives the pressurizing force transmitted from the joint cover portion (1342) and the insertion portion (1344) to pressurize the sealing portion (1325), thereby allowing the second joint (117) to be pressed against one side of the second panel (101) together with the sealing portion (1325).

The component joint includes a second component joint (135). The second component joint (135) may be configured to join an evaporator (148). The second component joint (135) may be referred to as an evaporator joining plate.

Figure 32 is a conceptual diagram showing a structure in which a component joint according to another embodiment of the present invention adheres a second storage chamber joint (520) to one side of a main body (100).

This embodiment differs from the embodiments of FIGS. 1 to 26 described above in that the sealing frame (530) seals the second storage room joint (520) and the insulation block (522) to one side of the second storage room (106).

However, this embodiment is similar to the embodiments of FIGS. 34 to 38 described above in that the second storage joint (520) and the insulation block (522) are pressed against each other using at least two press frames (530) spaced apart from each other in the X-axis direction, but some structures of the press frames (530) are different from those of the embodiments of FIGS. 34 to 38 described above.

The component joint includes a sealing frame (530). The sealing frame (530) can be sealed to an insulating block (522). The sealing frame (530) can be formed in a plate shape. The sealing frame (530) can extend in the Z-axis direction of the insulating block (522) between one side of the partition wall and one side of the fourth block portion (540). At least two sealing frames (530) can be arranged to be spaced apart from each other in the X-axis direction of the insulating block (522).

A coupling part (531) may be provided on at least one of the first end and the second end of the close frame (530). The coupling part (531) may extend in the Y-axis direction from at least one of the first end and the second end of the close frame (530). A coupling hole may be formed in the coupling part (531). A coupling member such as a screw may be coupled to the partition wall and the fourth block part (540) through the coupling hole.

Through this, the end of the sealing frame (530) can be coupled to the partition wall. The end of the sealing frame (530) can be coupled to the fourth block portion (540).

A frame joining groove may be formed on one side of the insulating block (522). The frame joining groove may be formed concavely to correspond to the sealing frame (530). The frame joining groove may extend in the Z-axis direction of the insulating block (522). The sealing frame (530) may be inserted and joined into the frame joining groove.

Through this, the frame joining groove can limit the movement of the sealing frame (530) in the X-axis direction. When the sealing frame (530) is inserted and joined into the frame joining groove, one side of the sealing frame (530) and one side of the insulation block (522) can form the same plane.

The sealing frame (530) can seal at least one of the insulating block (522) and the second storage joint (520) to one side of one of the first panels (1031) and/or the other of the first panels (1032).

The sealing frame (530) can limit movement of the insulation block (522) and/or the second storage joint (520) in the X-axis direction.

The sealing frame (530) can be connected to the insulation block (522) by a connecting member such as a screw. In this embodiment, the sealing frame (530) located at the part where the second joint (521) of the second storage room joint (520) and the insulation block (522) are connected is shown connected by a connecting member.

A connecting frame (533) can be placed between at least two sealing frames (530). The connecting frame (533) can extend in the X-axis direction along the insulating block (522). The connecting frame (533) can connect at least two sealing frames (530).

A second storage drawer guide (534) may be coupled to one side of the insulation block (522). The second storage drawer guide (534) may extend in the X-axis direction along the insulation block (522). At least two second storage drawer guides (534) may be arranged spaced apart from each other in the Z-axis direction of the insulation block (522).

The drawer guide (534) may be provided with a guide projection (5341). The guide projection (5341) may extend in the longitudinal direction of the drawer guide (534). An accommodating portion (5342) may be formed between at least two guide projections (5341). An insertion projection may be formed to protrude from a side of the drawer. The insertion projection of the drawer may be inserted into and coupled with the accommodating portion (5342) when the drawer is drawn in and out.

The second storage drawer guide (534) can intersect the contact frame (530) in one direction (e.g., perpendicularly to each other). The second storage drawer guide (534) can be arranged to cover the contact frame (530). In this way, the second storage drawer guide (534) can restrict the contact frame (530) from moving in the Y-axis direction.

The second storage drawer guide (534) can be coupled to the insulation block (522) by a coupling member such as a screw or the like. A coupling hole (428) can be formed in at least one of the first end and the second end of the second storage drawer guide (534). The coupling member penetrates the coupling hole (428) of the drawer guide (534) and the coupling hole (428) of the insulation block (522) to be coupled, thereby allowing the drawer guide (534) and the insulation block (522) to be coupled to each other.

, the sealing frame is bonded by sealing the insulating block (522) to one side of one of the first panels (1031) and/or the other side of the first panels (1032), so that the insulating block (522) and the second storage drawer guide (534) can be bonded to one of the first panels (1031) and/or the other side of the first panels (1032).

The second storage room drawer guide (534) can be spaced apart in the Z-axis direction at a predetermined interval from at least one of the third insulation block (523) of the second storage room (106), the other side of the third insulation block (523) of the second storage room (106), and the first block portion (242) of the fourth insulation block (539) of the second storage room (106). Through this, at least one of the third insulation block (523) and the fourth insulation block (539) can be tightly coupled to one of the first panels (1031) and/or the other one of the first panels (1032).

Accordingly, the Z-axis-extended contact frame (530) and the X-axis-extended second storage drawer guide (534) can contact the third insulation block (523) and the fourth insulation block (539) of the second storage room (106) to one side of one of the first panels (1031) and/or the other side of the first panels (1032).

Since other components are identical or similar to the embodiments of FIGS. 1 to 32 described above, duplicate descriptions will be omitted.

Figure 33 is a conceptual diagram showing the appearance before and after a partition wall (620) is joined to one side of an insulating block (522) of a second storage room (106) according to another embodiment of the present invention.

The insulating block (522) located in the second storage room (106) can be further extended in one direction to surround one side and the other side of the partition wall (620).

An insertion groove (624) into which an end of a partition wall (620) is inserted and joined can be formed on one end surface of an insulating block (522).

The insertion groove (624) may extend in the X-axis direction of the insulation block (522). The width of the insertion groove (624) in the Z-axis direction may be formed to become narrower from the first end to the second end of the third insulation block (523).

A side guide portion (621) may be formed to protrude in the Y-axis direction on one side of the partition wall (620). The side guide portion (621) may be formed to correspond to the insertion groove (624). The width of the side guide portion (621) in the Z-axis direction may be formed to become narrower from the first end of the insulation block (522) to the second end.

Through this, the side guide part (621) of the partition wall (620) can be easily inserted and connected into the insertion groove (624).

When the partition wall (620) is inserted and joined between at least two insulating blocks (522) located on at least one side of one of the first panels (1031) and one side of the other of the first panels (1032), the insulating blocks (522) can be tightly joined to one of the first panels (1031) and/or the other of the first panels (1032).

A duct connection part (622) may be formed to penetrate in the Z-axis direction at an end of the partition wall (620). The duct connection part (622) is a hole that forms a path for connecting the evaporator receiving part (5342) (424) of the second storage room (106) and the multi-duct of the first storage room (105). The duct connection part (622) may be arranged at the center of the end of the partition wall (620).

A return duct forming portion (623) may be formed in a portion of the partition wall (620) (e.g., the left and/or right ends of the rear end). The return duct forming portion (623) may be formed to be sunken in one direction (e.g., in one direction (e.g., forward)) in a portion of the partition wall (620) (e.g., the left and/or right ends of the rear end). The return duct forming portion (623) forms a path connecting the first storage room (105) and the second storage room (106) so that cold air in the first storage room (105) is circulated to the second storage room (106).

Since other components are identical or similar to the embodiments of FIGS. 1 to 32 described above, duplicate descriptions will be omitted.

Therefore, according to the present invention, a body (100) of a refrigerator is manufactured by assembling at least two panels (101, 102, 103, 104) made of vacuum insulation, and a joint (110) made of insulation material (112) is arranged at a corner where a plurality of vacuum insulation panels are connected to reinforce insulation of the corner.

Second, a bolt plate (109) may be installed on one side of at least two panels (101, 102, 103, 104). A bolt portion (1095) is formed protrudingly on the bolt plate (109). A joint (110) is provided with a joining portion (1164, 118, 124) in which a joining hole is formed. The bolt portion (1095) penetrates the joining hole (428) of the joining portion, and as the nut is joined to the bolt portion (3281), the joint (110) can be easily joined to one side of the main body (100), such as the second panel (101), by the bolt plate.

Third, the insulation blocks (230, 323, 427, 439) can be formed integrally at the joints (220, 320, 420). The insulation blocks (230, 323, 427, 439) can be expanded to the insulation area of the joints (220, 320, 420). The insulation blocks (230, 323, 427, 439) can be arranged by utilizing a space that does not change the high internal capacity of the refrigerator.

Fourth, the insulating block (230) can be joined by a bolt plate (229) installed on one side of the main body (100). A joining hole is formed in the insulating block (230). The bolt portion (2291) of the bolt plate (229) penetrates the joining hole of the insulating block (230), and as the nut is joined to the bolt portion (2291), the insulating block (230) can be easily joined to one side of the main body (100), such as the second panel (101) and one of the first panels (1031) and/or the other one of the first panels (1032), by the bolt plate (229).

Fifth, the sealing frame (330, 430, 530) can be joined to one side of the joint (320, 420, 520) or the insulating block (522) in which the joint (320) is formed integrally. A joining hole (428) is formed in the sealing frame (330, 430, 530). The sealing frame (330, 430, 530) can be joined to one side of the main body (100) by a bolt plate (328) or can be joined without a bolt plate. Since a connecting member such as a screw is connected by penetrating the connecting hole of the insulating block (427, 439, 522) and the connecting hole (428) of the sealing frame (430, 530), the sealing frame (430, 530) can seal the insulating block (427, 439, 522) to one side of the main body (100) without a bolt plate. An extension rib (114, 125) can be extended along the longitudinal direction of the joint (320, 420, 520). The sealing frame (330, 430, 530) can seal the joint (320) to one side of the main body (100) by pressing the extension rib (114, 125) or directly pressing the joint (320).

Sixth, components arranged inside the main body (100), such as a shelf (130), a drawer, etc., may be provided with a separate first component joint (131) and may be joined to one surface of the main body (100). The first component joint (131) having a through hole (1324) or a drawer guide (1411, 1421) may be easily joined to one surface of the main body (100) by the bolt plate (109). The bolt portion (1095) of the bolt plate (109) passes through the joining hole of the first component joint (131), and as the nut is joined to the bolt portion (1095), the shelf (130) may be easily joined to one surface of the main body (100). The bolt portion (1091, 2291) of the bolt plate (109, 229) passes through the joining hole of the drawer guide (1411, 1421, 227, 228), and as the nut is joined to the bolt portion (1091, 2291), the drawer guide (1411, 1421, 227, 228) can be easily joined to one surface of the main body (100).

Seventh, the end of the sealing frame (430, 530) can be joined to the partition wall (620). The end of the sealing frame (430, 530) can be joined to the fourth block part (440, 540), which is the insulating block (439, 522) of the fourth panel (104). Since the drawer guide (429, 534) is joined to the insulating block (439, 522) by a joining member such as a screw, the sealing frame (530) can easily seal and join at least one of the insulating block (439, 522) and the drawer guide (429, 534) to one surface of the first panel and/or the second panel (103).

Eighth, the sealing frame (430, 530) is joined to one side of the insulating block (439, 522) formed integrally with the second storage joint (520). Through this, the sealing frame (430, 530) can easily join the second storage joint (520) or the insulating block (439, 522) to one side of the main body (100). Since the sealing frame (430, 530) does not require a bolt plate, it not only blocks heat leakage through the corners, but also is advantageous in improving insulation performance.
